SPECIFICATION forming part of Letters Patent No 782,137, dated February 7, 1905.

Application filed March 8, 1904. Serial No. 197,193.

1'0 all whom, it may concern.-

Be it known that we,VVILLIAM G. J AMI ESON, residing at St. Louis, and JosEPH R. DURBAN, residing at ebster Groves, Missouri, citizens of the United States, have invented certain new and useful Improvements in Music-Leaf Turners, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to music-leaf turners; and it consists of the novel features herein shown, described, and claimed.

1n the drawings, Figure 1 is a front elevation of a music-leaf turner embodying the principles of our invention. Fig. 2 is a side elevation showing the music-leaf turner in position for use upon the shelf of a musical instrument, the musical instrument being broken away and the view being taken looking in the direction of thearrow 2 in Fig. 1. Fig. 3 is an enlarged detail perspective of the operating mechanism, parts being broken away to economize'space. Fig. I is a view analogous to Fig. 2 upon an enlarged scale, the leaf-turning arms being broken away and the base being shown in section. Fig. 5 is a cross-section on the line 5 5 of Fig. 1. Fig. 6 is an enlarged detail perspective of the trip mechanism.

Referring to the drawings in detail, the base 10 is a rectangular metallic block of sufficient height to hold the music-leaf turner in position, and a sheet 11 of felt is placed on the bottom and back side of the base to protect the shelf 12 of the musical instrument. Rubber feet 13 are placed under the forward corners of the base 10 to tilt the music-leaf turner backwardly against the front face 14 of the musical instrument and keep the musicleaf turner from tipping forwardly and falling from the shelf 12.

The cover-holders comprise wires bent to form posts 15, the horizontal arms 16 extending outwardly from the upper ends of the posts, the U shaped clamps 17 extending downwardly and backwardly and upwardly from the outer ends of the arms 16, said posts being securely anchored in the ends of the base 10.

'backwardly and forwardly.

A supporting-label: 18 extends forwardly and upwardly from the base 10, and the music-clamp extends upwardly from the forward part of this block, said clamp comprising the rigid jaw 19, secured at its lower end to the block 18 by the bracket 20, the sheetmetalguide 21, secured to the back side of the jaw 19 and projecting laterally, the movable jaw 22, mounted beside the jaw 19 in front of the guide 21, the expansive coil-spring 23, inserted between the spring-seat 2 1, rigidly secured to the block 18, the spring-seat 25, seemed to the lower end of the movable jaw 22, the spring-latch 26, hinged to the upper end of the rigid jaw 19 and engaging the catch 27 at the upper end of the movable jaw 22, the tension of the spring 23 and of the spring-latch 26 being exerted to press the movable jaw 22 against the binding edges of the music, so as to lirmly grip the music-sheets between the jaws 22 and 19. A stop 28 extends laterally and forwardly from the guide 21 to limit the outward motion of the movable jaw 22, so that when the spring-latch 26 is disengaged from the catch 27 the upper end of the jaw 22 may be swung outwardly against the stop 28, and the music-leaves may then be inserted between the jaws against the guide 21, and then the lower outer parts of the covers or outer sheets may be inserted into the clamps 17 leaving the intermediate sheets free to turn A bracket-plate 29 is rigidly secured to the front face of the block 18, and brackets 30 31 32 33 34 extend forwardly from said bracket-plate, and a pivot-pin 35 is mounted vertically through said brackets.

The music-leaf-turning heads 36 37 38 3 are rectangular blocks pivotally mounted upon the pivot-pin 35, and the musicleafturning arms 10 etl 42 13 are secured to the outer ends of the heads 36 37 38 39, the outer ends of said arms being bent upwardly into substantially the same plane as shown in Fig. 1. The music-leaf clamp-blocks 4A a5 16 47 are adjustably mounted upon the arms 10 a1 4.2 13 by means of set-screws 18, screw-seated in the blocks and engaging the arms, so that said blocks may be adjusted to or from the pivotpin 35.

The music-leaf-turning clamps 19 5O 51 52 are plates of sheet metal secured to the sides of'the blocks 4A 4:5 4:6 17 and bent toward each other, so that the music leaves may be inserted downwardly between the strips of metal, the tension of said strips being exerted toward each other, so as to grip the sheets.

The outer ends 53 5a 55 of the arms 10 41 42 are bent downwardly to form stops, the stop 55 being in front of the arm a3, the stop 54 being in front of the arm 42, and the stop 53 being in front of the arm 11, so that when the music-leaves are inserted into the clampsthe first intermediate page into the clamp 49, the second intermediate page into the clamp 50, the third intermediate page into the clamp 51, and the fourth page into the clamp 52- the clamps swing into the position shown in Fig. 1, so as to expose the first sheet of music. The sheets can only be turned or arms operated in rotation. in other words, it will be impossible for the clamp 52 to get in front of the clamp 51, and so on.

The springs 56 57 58 59 have coiled central portions through which the pivot-pin 35 is inserted, one end of each spring being secured to the block 18, the other end of the springs being secured to the blocks 36 37 38 39, the tension of said springs being exerted to swing the arms 10 41 42 13 as required to turn the leaves of music from one side to the other.

The catch-pins 6O 61 62 63 extend from the right-hand face of the block 18, and the springcatches 6 1 65 66 67 are carried by the blocks 36 37 38 39, so as to engage said catch-pins and hold said arms against the tension of the springs 56 57 58 59.

A bar 68 is mounted to slide vertically in the block 18, the lower end of said bar being bent forwardly to carry the handle 69, and an arm 70 extends laterally from the bar 68 in position to engage the catches 6 1 65 66 67, so that by manually depressing the handle 69 the catch 64 will be disengaged from the pin 60 and the first sheet of music will be turned by the tension of the spring 56, swinging the arm 40 to the left, as shown in dotted lines in Fig. 1. A stop-arm 71 extends from the bar 68 in the form of nearly a half-circle, so that when the handle 69 is depressed to release the catch 6 1 from the pin 60 the stop-arm 71 will engage the arm 10 and hold the bar 68 from being further depressed, thus preventing the liability of two or more of the leaves being turned at once without such intention. \Vhen the arm 10 swings against the left-hand post 15, the second sheet of music is exposed to View, and when the handle 69 is again dopressed the arm 7 0 will engage the catch 65 and release the second sheet of music, and so on until the four sheets have been turned. Then the handle 69 is manually elevated, the arm a0 manually engaged to swing the clamp 4:9 back to its normal position, thus swinging all of the clamps back to their normal positions.

A brace 72 extends downwardly from the block 18 behind the bar 68 to prevent the bar bending downwardly when the handle 69 is depressed to release the catches 66 67.

In a music-leaf turner; a suitable base; music-leafturning arms pivotally connected to the base; springs connecting said arms to the base, the tension of said springs being exerted to turn the leaves; catches for holding said arms against the tension of the springs; clamps carried by said arms to engage the leaves; and means of releasing said catches; said means comprising a bar mounted to slide vertically in the base; a handle extending from the bar; an arm extending laterally from the bar to engage the catches; and a stop-arm ex tending from the bar to engage the musicleafturning arms; substantially as specilied.
